Cannot get right sidebar to show on certain pages

I created a WP e-commerce site for a friend a year ago and haven't touched it since initially getting things working. She contacted me recently that she was unable to add new items so I upgraded the WP e-commerce plugin which resolved issue with being unable to add new products, but now her site has a handful of other display issues. The first issue is that I'm attempting to display 3 widgets in the right sidebar and it's not appearing on at least 2 pages (Categories and Products if that means anything). I have every checkbox checked in the RIGHT sidebar: Display on section and have not explicitly entered any page IDs to exclude. On the Categories page, like I said, there is no sidebar. And when I inspect the markup the tr#bodyrow only has a td#middle; there is no td#right.

Any input would be appreciated.

PS. I'm using Atahualpa 3.7.12
